What is the Blue Zone Diet Plan?

The Blue Zone Diet is based on the lifestyles and eating habits of people living in “Blue Zones” — regions around the world. These are places where individuals live remarkably long lives.

Blue Zone Regions

The Blue Zones include places like:
  • Okinawa, Japan
  • Sardinia, Italy
  • Nicoya, Costa Rica
  • Ikaria, Greece
  • Loma Linda, California.

In most Blue Zones found throughout the world, residents of these areas focus on eating the whole foods that are available to them during the year. During the harvesting months, people in the Blue Zones eat many varieties of garden vegetables, while during the winter months, they rely on pickled or dried versions of these foods that have been minimally processed.

The Blue Zone Diet as a whole emphasizes the importance of eating whole, plant-based foods.

At the same time, the diet encourages practitioners to limit or eliminate their consumption of processed foods, animal products, and added sugars.

How Does the Blue Zones Diet Work? Meet the 11 Blue Zone Guidelines

Blue Zone Diet Guidelines

Through a combination of experimentation and research, Blue Zone Diet experts have crafted a series of guidelines that serve as the “rules” for this particular diet.


The ultimate goal is to develop a healthy lifestyle rather than a short-term diet. You do this by focusing on nourishing the body with nutrient-rich, unprocessed options that their research associates with longevity and better overall health.

The Blue Zone Diet is composed of the following 10 guidelines:

  1. Retreat from meat by eating roughly 2 oz. or less of meat no more than 5 times per month

  2. Reduce your dairy intake significantly

  3. Slash sugar intake by consuming only 28 grams (or 7 teaspoons) of added sugars daily. Better yet adopt principles from the SOS-Free Diet.

  4. Eliminate eggs by eating no more than 3 eggs per week

  5. Go easy on fish, eating fewer than 3 oz. of fish up to 3 times per week

  6. Snack on nuts, aiming for 1 to 2 handfuls per day

  7. Drink mostly water and aim for roughly 7 glasses per day — coffee, tea, and wine can be consumed in moderation

  8. Get in your daily dose of beans by eating a half-cup to one cup of beans per day

  9. Go “wholly whole” with single-ingredient, raw, cooked, ground, or fermented foods that are not highly processed

  10. Aim to eat a diet that is 95% to 100% plant-based

Foods to Eat & Foods to Avoid on a Blue Zones Diet

Blue Zone Diet Foods to AvoidTo fully embrace the Blue Zone Diet, it's essential to make conscious choices about the foods you consume.


While it may take time to transition to a fully plant-based diet, you can begin by taking smaller steps and focusing on adding and eliminating foods based on the following lists:



Foods to Eat on the Blue Zones Diet

Blue Zone Diet Foods


  • Dark, Leafy Greens: Leafy greens like kale, spinach, and collard greens are rich in vitamins, minerals, and antioxidants. Plus, these greens are high in dietary fiber, helping to support your overall digestive function and gut health.

  • Blueberries: These tiny powerhouses are packed with antioxidants that support brain health and fight inflammation. Known as a superfood, blueberries are nutrient-dense and make a great snack on their own. Blend them into smoothies or add them into baked treats!

  • Healthy Oils: Incorporate healthy oils, like olive oil and avocado oil, which are known for their heart-protective benefits. These oils are also popular for their anti-inflammatory effects, which can be particularly helpful for anyone dealing with chronic inflammatory conditions.

  • Beans and Legumes: Beans and legumes provide a great source of protein, fiber, and essential nutrients. Additionally, beans and legumes are often a primary alternative for animal proteins, helping to keep you feeling full and satiated as you transition away from eating meats.

  • Whole Grain Bread or Sourdough: Whole grains are a staple in the Blue Zone Diet, providing sustained energy and fiber. Sourdough bread specifically is known for its digestive benefits and is often regarded as easier to digest than other bread types.

  • Nuts: Nuts offer healthy fats, protein, and important nutrients that support heart health. When eaten as a snack, nuts help maintain or reduce your weight, as well as provide you with a low-calorie snack that’s filling without being calorically dense.

  • "Whole" Foods: Focus on eating foods that are as close to their natural state as possible, and avoid processed or refined options. For example, opt for fresh berries over dried berries with added sugars — or, alternatively, dry the berries yourself to ensure no unnecessary sugars or additives make their way into your dried fruits.

Foods to Avoid on the Blue Zones Diet

  • Limit Meat Consumption: Reducing meat intake is a fundamental aspect of the Blue Zone Diet. Consider meat a rare indulgence rather than a regular staple. Not only can this greatly benefit your health, but you’re also likely to notice a significant drop in your weekly grocery bills by cutting back on the meat.

  • Reduce Fish Intake: While fish can be part of a Blue Zone Diet, moderation is key. Aim to eat small portions of fish a few times a week. Additionally, the Blue Zones Diet also emphasizes sustainability as part of its overall goal, meaning you should select fish that are common and abundant (like anchovies, Atlantic mackerel, or Pacific Salmon).

  • Cut Back on Dairy: Dairy consumption is limited in the Blue Zone Diet. Explore plant-based alternatives for milk, cheese, and yogurt — such as almond or oat-based milk products. Limiting your dairy consumption can also lead to drastic improvements in your gut health, especially if you are used to overconsuming dairy in your previous diet and lifestyle.

  • Eliminate Eggs: Eggs are excluded from the Blue Zone Diet due to the cholesterol content found in the yolk. If you absolutely need your morning eggs, you should opt for egg whites with the yolk removed whenever possible. For baking purposes, ingredients like applesauce, non-dairy yogurt, and silken tofu work as egg replacements.

  • Minimize Sugar: Slash your sugar intake by opting for whole, naturally sweet foods like fruits. Added sugars can be a major culprit for a variety of health issues and can even become addictive if eaten too frequently and in too high of quantities. If you already have an over-reliance on added sugars, scale your intake back slowly to avoid unwanted side effects like fatigue and headaches.

  • Prioritize Water: Water should be your primary beverage, minimizing the consumption of sugary drinks and excessive amounts of caffeine. Additionally, you should limit your intake of alcohol as much as possible — whenever you do have an alcoholic beverage, be highly mindful of the sugar content found within your beverage of choice.

Now, we can’t stand over your shoulder and make you drink water, but Whole Harvest’s ready-to-eat, 100% whole food plant-based meals help you easily avoid the rest of this list while eating delicious meals!

The Potential Health Benefits of a Blue Zones Diet

Blue Zone Eating

Following the Blue Zones Diet is easier on your wallet but it also provides you with a plethora of advantages that help you maintain your health and well-being long-term.


The potential health benefits of the Blue Zones Diet include:

  • Weight Loss: The emphasis on whole, plant-based foods can support weight loss and weight management. Processed foods with a high level of added sugars are often calorically dense and can even cause inflammation and bloating when eaten in excess. Switching to the Blue Zones Diet helps reduce bloating and inflammation, as well as your overall calorie intake. Ultimately, this can lead to more sustainable weight loss.

  • Diabetes: The diet's low sugar content and focus on complex carbohydrates can help manage blood sugar levels — something that is crucial for those living with or at risk of developing diabetes. Additionally, eating a diet with a high fiber content (such as the Blue Zones Diet) has been shown to further reduce your risk of type 2 diabetes.

  • Cancer & Heart Disease: The consumption of antioxidant-rich foods like berries and greens may contribute to cancer prevention by helping to rid the body of free radicals and other harmful toxins. Meanwhile, the Blue Zone Diet's emphasis on healthy fats, fiber, and plant-based proteins can support cardiovascular health.

Anytime you are working to reduce the impact of or prevent specific health conditions — like diabetes, cancer, and heart disease — it is of the utmost importance to involve your primary healthcare provider in your decision and transition. With the guidance of the Blue Zone Diet paired with the personalized expertise of your medical provider, you can ensure your diet is optimized for your needs.

What are the potential Risks of The Blue Zone Diet? While the Blue Zone Diet offers many benefits, it's important to maintain a mindful approach.

Dietary changes of any kind can result in negative side effects in the beginning, even if the ultimate outcome is positive. Moreover, it’s important to consider how these dietary changes may affect your body and your overall understanding of nutrition.

Here are three important factors to consider when switching to the Blue Zones Diet:

  • Nutrient Deficiencies: Without careful planning, certain nutrients like vitamin B12, iron, and omega-3 fatty acids may be lacking in your diet, especially if animal products are eliminated entirely. This further stresses the importance of working with a medical professional during your dietary transition, as they can guide you on where to get your nutrients from and how to create a balanced diet that can sustain your health long-term.

  • Social Challenges: Adhering to the Blue Zones Diet can be challenging in social situations and when dining out, where options may be limited. While you should try to stick to the guidelines of the Blue Zones Diet, remember that moderation is key — you need to find the right balance between your social outings and honoring your dietary choices.|

  • Dietary Side Effects: If you typically eat hefty amounts of sugar and processed foods, switching to a Blue Zones Diet can initially cause some bothersome side effects. These may include headaches, mood swings, and fatigue. Additionally, introducing more dietary fiber to your diet can impact your gut significantly, resulting in irregular or increased bowel movements or flatulence. But don’t give up! In most cases, these side effects should clear up after the first two to three weeks.

3 Key Tips on How to Eat Out on a Blue Zones Diet

The social aspect of the Blue Zones Diet can be one of the hardest aspects to overcome, especially if you have a thriving social circle and lifestyle.

To help you on your journey to starting the Blue Zones Diet, we have outlined three essential tips for eating out at social events while following this diet:

  • Research Beforehand: Before a night out, look up the menus in advance and choose restaurants that offer whole food plant-based options. It can also be beneficial to explain your circumstances to your friends and offer up suggestions for restaurants that meet everyone’s dietary needs.

  • Customize Your Orders: Don't hesitate to ask for modifications to dishes to make them more in line with your dietary preferences. If a restaurant does not allow modifications, either avoid these restaurants in the future or treat them as a special once-per-month treat.

  • Come Prepared: Seeing your friends eating all the foods you are trying to avoid makes it tempting to break your resolve. To combat these feelings, consider eating a small, healthy snack before heading out to avoid hunger-driven impulse choices.
